Got mine from Justin at RK. Your best bet is to go directly to rangerknives.com for contact info, and either call or email Justin regarding a custom shiv. His standard production shiv is para wrapped, not sure if they are predrilled other than for a lanyard. Just tell him what you want and he will create it at a cost not much more than the standard. They are tough little knives, 1095 carbon steel, 4 inch blade and about 8.5 inches LOA. Looks like mine is 3/8 thick at the spine. Pick a grind and handle material and you are good to go. Justin is so easy to deal with that it probably won't be your last knife from him
